Case studies - Research and technological solutions to prevent sand production in the gas wells from the Getic Depression
2021
A frequent challenge encountered in the exploitation of mature gas fields located in the Getic Depression is sand production. Causes of sand production are mainly related to degree of rock consolidation, lithology, increasing water production and production rates. The effects of sand production are multiple such us low productivity of the gas wells, accumulation into the surface equipment, erosion of downhole and surface equipment, plugging the perforation zone and casing damage. The current paper will address the sand production- challenges and new perspectives in remedial work of wells which are producing from gas reservoirs located in Getic Depression. The article presents through some c…
Surface–bottom relationships in the Gulf of Salerno (Tyrrhenian Sea) over the last 34 kyr: Compositional data analysis of palaeontological proxies an…
2009
The palaeontological, geochemical and mineralogical records of core GNS84-C106 were analysed in order to reconstruct palaeohydrological changes and palaeoproductivity patterns in the Gulf of Salerno for the last 34 kyr. This approach, including compositional analysis of planktonic and benthic assemblages, gave an insight into the relationships between continental, sea surface and bottom environmental changes. The main source of variability of planktonic and benthic assemblages is related respectively to sea surface temperature and palaeobathymetry. Interrelated changes in surface salinity, nutrients, density gradient in the water column and organic fluxes at the bottom act as a secondary fa…
Paradigms as triggers of semantic change: Demonstrative adverbs in Catalan and Spanish
2015
This paper sets out to analyse the development of demonstrative adverbs of place in Catalan and Spanish. The main questions dealt with in this study are the following: (i) why two-term and three-term deictic systems often display a certain lack of stability so that diachronically two-term systems sometimes become three-term (as in old Catalan and Spanish) or, the other way round, three-term systems become two-term (like in late Latin and in Catalan during the modern era); (ii) if the most normal and expected development is for deictic systems to take on anaphoric values, why in the case of the adverb aquí ('near the speaker and/or addressee') in Catalan and the adverb ahí ('near the address…
Root Canal Morphology and Configuration of 179 Maxillary First Molars by Means of Micro-computed Tomography: An Ex Vivo Study
2015
Introduction The objective of this study was to propose a root canal configuration description method and to investigate the root canal system morphology of the maxillary first molar by means of micro-computed tomographic imaging. Methods The root canal configuration, foramina, and accessory canal frequency of 179 maxillary first molars were investigated by means of micro-computed tomographic imaging and 3-dimensional software imaging. The root canal configuration and main foramina number are described from coronal to apical with a 4-digit system. Results The most frequent root canal configurations were 1-1-1/1 (45.8%), 2-2-2/2 (25.1%) and 2-2-1/1 (10.1%) in mesiobuccal roots and 1-1-1/1 in…
Extracerebral biopsies in neurodegenerative diseases of childhood
1999
Abstract Among the numerous neurodegenerative diseases in children few may allow morphological diagnosis by extracerebral biopsy. These encompass neurometabolic conditions, foremost lysosomal disorders, but also peroxisomal and mitochondrial diseases marked by disease- or group-specific organelles. Largely, these neurometabolic conditions can also be diagnosed by biochemical and increasingly by molecular genetic techniques. However, there are a few neurodegenerative diseases which do not allow either biochemical or molecular genetic diagnosis and, thus, rely on biopsy of extracerebral tissues, so-called ‘essential’ biopsies to achieve a diagnosis during the patient's life. Among these few d…
Intestinal tuberculosis as a cause of chronic diarrhoea among patients with human immunodeficiency virus infection: report of two cases.
2001
In Western countries human immunodeficiency virus infection is considered the main risk factor of tuberculous disease, its incidence being 500 times higher in HIV-infected patients than in the general population. Despite the disease frequently present in these patients with extraintestinal manifestations, intestinal localization is rarely observed and often as a consequence of complications such as acute gastrointestinal bleeding or perforation. The diagnosis of intestinal tuberculosis is difficult and is often delayed due to the lack of specific signs and symptoms as well as the low sensitivity of routine methods. A review of the literature is made and personal experience in the diagnosis …
Koira haudattuna : koiran ja sen kuoleman representoiminen blogiteksteissä
2015
Pro gradussani tutkin, kuinka koiransa menettäneet ihmiset luovat internetissä kuvaa menehtyneistä koiristaan ja koiran kuolemasta. Tutkimukseni tavoitteena on selvittää, millaista kuvaa koirista ja niiden kuolemasta luodaan blogeissa, ja millaisin kielen keinoin tämä tapahtuu. Aihetta ei ole suomen kielen näkökulmasta aiemmin tutkittu, vaikka koiran kuolema koskettaakin meistä monia. Tutkimuskysymykseni ovat seuraavanlaiset: Millaisilla kielen keinoilla menehtynyttä koiraa representoidaan blogeissa? Millaisilla kielen keinoilla koiran kuolemaa representoidaan blogeissa? Millaisien diskurssien kautta koiraa ja sen kuolemaa kuvataan, ja millainen kuva koirasta ja kuolemasta muodostuu? Tutkim…
Le parole della musica nella Divina Commedia
2018
L'Autrice analizza un ampio corpus delle parole legate alla musica nella Divina Commedia, esaminando le differenze nelle occorrenze delle tre cantiche e giustificando le differenze stesse. Dei lessemi viene presentata un'analisi condotta secondo gli approcci propri della linguistica cognitiva, nello specifico quello semasiologico e quello onomasiologico. Mentre la parola 'musica ' non è attesta, molto diffuso è il termine 'canto' nel valore proprio e in quello metaforico. La rete di relazioni semantiche mostra una notevole ambiguità, come è dimostrato per quanto riguarda il canto di Casella, il secondo del Purgatorio. Il lavoro intende entrare in qualche modo nel laboratorio di scrittura de…
Divšķautņu asinszāle farmaceitiskajā aprūpē
2020
Mūsdienās augu valsts līdzekļi ir plaši izmantoti visā pasaulē, tai skaitā arī Latvijā. Divšķautņu asinszāle aug Latvijas teritorijā un tās saturošie preparāti ir pieejami Latvijas aptiekās, kaut arī ne tik plašā sortimenā. Pēdējos gados, divšķautņu asinszāles produktu patēriņš ievērojami palielinājas un šobrīd šīs augs ir viens no visvairāk patērētajiem augiem pasaulē. Paaugstinātā stresa līmeņa dēļ mūsu laikos liels cilvēku skaits cieš no depresijas un asinszāles antidepresīvais efekts un arī citas īpašības tiek plaši pētītas. Darba mērķis bija noteikt cik labi farmācijas speciālisti un divšķautņu asinszāles saturošo preparātu lietotāji (aptiekas klienti) ir informēti par šī auga īpašībām…
Valoda: nozīme un forma. Plašsaziņas līdzekļu valoda
2009
Šajā krājumā apkopotās publikācijas veidotas uz referātu pamata, kas nolasīti Latvijas Universitātes Filoloģijas un mākslas zinātņu fakultātē notikušajos semināros “Funkcionālie stili un runas žanri plašsaziņas līdzekļos” 2007. un 2008. gadā. Krājumā ietverti gan zinātniski, gan populārzinātniski raksti, kas adresēti plašam interesentu lokam. Sākumā aplūkoti vispārīgi jautājumi par publicistikas valodas vietu latviešu valodas funkcionālo paveidu sistēmā, pēc tam analizētas leksikas lietojuma īpatnības un daži plašsaziņas līdzekļu valodas gramatiskie aspekti, krājuma beigu daļā vairāki reklāmas un sludinājumu valodai veltīti raksti, kā arī pētījumi par lietišķā stila izmantojumu plašsaziņas …
